Question

我正在尝试对我的中继器进行数据绑定，但到目前为止还没有任何运气。有谁认为可以告诉我哪里出错了？我现在有两个函数，通过一些教程/示例，但我希望只有一个...也许不可能。谢谢！

HTML：

                <ItemTemplate>
                        <tr class="row">
                            <td><asp:Label ID="TitleLabel" runat="server" Text=""></asp:Label></td>
                            <td><asp:Label ID="NameLabel" runat="server" Text=""></asp:Label></td>
                            <td><asp:Label ID="PhoneLabel" runat="server" Text=""></asp:Label></td>
                            <td><asp:Label ID="EmailLabel" runat="server" Text=""></asp:Label></td>
                        </tr>
                </ItemTemplate>

VB

Protected Sub BindData()

    Dim oCommand As SqlCommand
    Dim oReader As SqlDataReader

    Try
        oCommand = DataAccess.GetSQLCommand("People_Retrieve", CommandType.StoredProcedure, SourceServer.ConnectionLocal)
        oCommand.Connection.ChangeDatabase("MyDatabase")

        oCommand.CommandTimeout() = 9000
        oReader = oCommand.ExecuteReader()

        PeopleRepeater.DataSource = oReader
        PeopleRepeater.DataBind()

    Catch ex As Exception
        ErrorHandler.HandleError(ex)
    Finally
        oReader.Close()
        oReader = Nothing
    End Try

End Sub

Protected Sub PeopleRepeater_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles PeopleRepeater.ItemDataBound

    Dim NameLabel As Label = CType(e.Item.FindControl("LabelName"), Label)
    NameLabel.Text = e.Item.DataItem("Name")

    Dim TitleLabel As Label = CType(e.Item.FindControl("TitleName"), Label)
    NameLabel.Text = e.Item.DataItem("Title")

    Dim PhoneLabel As Label = CType(e.Item.FindControl("PhoneName"), Label)
    NameLabel.Text = e.Item.DataItem("Phone")

    Dim EmailLabel As Label = CType(e.Item.FindControl("EmailName"), Label)
    NameLabel.Text = e.Item.DataItem("Email")

End Sub

Answer 1

使用SqlDataAdapter：

Using adap As New SqlDataAdapter(oCommand)
    Dim table As New DataTable()
    adap.Fill(table)

    PeopleRepeater.DataSource = table
    PeopleRepeater.DataBind()
End Using

我也没看到你打开连接的位置，所以你可能需要添加：

oCommand.Connection.Open()

Answer 2

按照步骤

创建名为“SelectPersonalDetails”
的存储过程
CREATE PROCEDURE SelectPersonalDetails

- 在此处添加存储过程的参数

@Email SYSNAME
```
AS

BEGIN
```
- 添加SET NOCOUNT ON以防止出现额外的结果集 - 干扰SELECT语句。

设置NOCOUNT ON;

- 在此处插入程序声明

开始尝试开始交易

BEGIN

SELECT Name，Title，Phone，Email FROM PersonalDetails

WHERE 电子邮件= @Email

END

COMMIT TRANSACTION

结束尝试

BEGIN CATCH
```
ROLLBACK TRANSACTION
DECLARE @ERR AS VARCHAR(500)
SELECT @ERR = ERROR_MESSAGE()   
RAISERROR(@ERR,16,1)

RETURN
```
END CATCH END

创建数据集以便在转发器中绑定数据。

public DataSet Get_PersonaldetailbasedEmail（） {

    try
    {
        DataSet oDS = new DataSet();
        SqlParameter[] oParam = new SqlParameter[1];

        oParam[0] = new SqlParameter("@Email", _sEmail);


        oDS = SqlHelper.ExecuteDataset(DataConnectionString,          CommandType.StoredProcedure, "SelectPersonalDetails", oParam);
        return oDS;
    }
    catch (Exception e)
    {
        ErrorMessage = e.Message;
        return null;
    }
}

注意：（i）SelectPersonalDetails是存储过程名称

  (ii) In order to select unique record from the table i have used emailid 

  (iii) I have assume the table name as PersonalDetails.

创建类似Personeldetails.ascx
的用户控制页面

/立GT; /立GT; /立GT; /立GT;

上面注意我有转发器的html代码，但我不知道如何在这个编辑器中解决。无论如何，转发器ID与转发器相同，标签ID与您的标签ID相同。

数据绑定

创建一个绑定数据的函数

public void FillArray（ArrayList alist） { ArrayList al = new ArrayList（）;

    foreach (Object objRow in alist)
    {
        string sTitle = ((DataRow)objRow)["Title"].ToString();
        string sName = ((DataRow)objRow)["Name"].ToString();
        string sPhone = ((DataRow)objRow)["Phone"].ToString();
       string sMail = ((DataRow)objRow)["Mail"].ToString();        

        al.Add(new string[]{ sTitle,sName,sPhone,sMail});


    }
    PeopleRepeater.DataSource = al;
    PeopleRepeater.DataBind();


}

现在名为Item databound

if（e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem） { string [] itemArray =（（string []）e.Item.DataItem）;

        Label myTitle = (Lable)e.Item.FindControl("TitleLabel");
        Label myName = (Label)e.Item.FindControl("NameLabel");
        Label myPhone = (Label)e.Item.FindControl("PhoneLabel");
        Label myEmail = (Label)e.Item.FindControl("EmailLabel");

        myTitle.Text = itemArray[0];
        myName.Text = itemArray[1];
        myPhone.Text = itemArray[2];
        myEmail.Text = itemArray[3];




    }
